Title: Folding wings of aerogenerator
Inventor: JEON YONG JUN
IPC: F03D1/06
Filed: 2021-03-25
Abstract: The present invention relates to an elastic-restoration type foldable wing for a wind turbine and, more specifically, to an elastic-restoration type foldable wing for a wind turbine, wherein since blades are made to be tilted backward by a spring, even in case of a super strong wind such as a typhoon, the blades are tilted backward separately in accordance with wind pressure exerted to each of the blades without separate pitch control, and when the wind pressure exerted to the blades decreases, the blades are automatically restored forward by elasticity, thereby preventing damage to the wing and reducing a load applied to a wind turbine and fatigue applied to the blades. In accordance with one advisable embodiment of the present invention, the wing for a wind turbine, which is provided to a wind power facility and actuating a generator through a power transmission mechanism transmitting a rotation force when rotated by wind power, includes: a rotary shaft formed horizontally, having a fixing part formed at a front end, and having a plurality of hinge parts formed to be protruding from an outer circumferential surface of the fixing part; a blade having one shaft part formed on one side, and fixed to the hinge parts through a shaft pin to be rotated around the shaft pin; and a spring having both ends connected with the fixing part of the rotary shaft and the blade respectively, in a state in which the blade is unfolded orthogonal to the rotary shaft, and formed to be elastic.
